GLOVE OR GARMENT FASTENER.

SPECIFICATION forming part of Letters Patent No. 502,404, dated August1, 1893.

Application filed March 22, 1893. Serial No. 467.223. (No model.)

To all whom it may concern,.-

Be it known that I, EDWIN J. KRAETZER, of Cambridge, in the county ofMiddlesex and Commonwealth of Massachusetts, have invented anImprovement in Glove and Garment Fasteners, of which the following is afull, clear, and exact specification.

My invention relates to that class of fasteners wherein there are twomain parts,--a socket member and a stud member, and consists of animproved socket member, the construction of which is hereinafterdescribed in detail.

Referring to the accompanying drawings wherein like letters representlike parts, Figure l shows a cross section of my socket proper and cap.

which the spring is made. Fig. 3 is a plan of my spring. Fig. 4 is aplan of my supf porting ring. Fig. 5 is a vertical section of my socketmember attached to any material. Fig. 6 is an elevation of the studmember.

Referring to Fig. l, the part of my socket which forms the cap and restson top of the material is composed of the following pieces: the capproper A, whose outside edge is turned down and over the edge of thewasher M, which fits inside the cap and confines beneath it the anvilplate N. The socket proper B, which rests beneath andis riveted throughthe material into the cap, consists of the eyelet H, the spring C, thecollet I, and the supporting ring J. The eyelet H has an upright barrel,which, when the two parts of the socket are pressed together, piercesthe material, is spread outward by the anvil plate N, and clinchesbeneath the washer M, thus firmly riveting the two parts together. Theeyelet, below the barrel, flares outward forming the shoulder d, and thehorizontal fiange a. This ange rests upon the horizontal flange c of thespring C, which in turn rests upon the bottom of the collet I, whoseedge is turned up and over the two ilanges a and c, thus holding thespring in place between the collet and the flaring portion of theeyelet. The spring C, I preferably strike up from spring metal, and oneway of forming it is from the blank shown in Fig. 2. The center of theblank is drawn down and Fig. 2 shows the blank froml pierced in the formshown in Fig. 2, leaving the horizontal flange, which is finally turneddown and out, as shown in Fig. 3.

Fig. 3 shows a plan of my completed annular bow curved spring. Theflange C, as

'hereinbefore stated is preferably embraced between the collet I, andthe flange a. of the eyelet. The crown e of the spring preferably comesunder the shoulder o, of the eyelet, and the spring edge CZ extendsdirectly around 6o the entrance hole of the stud in the collet I, andmay be substantially at right angles to the edge of the hole in thecollet I.

I preferably provide my annular curved spring with three slits o, thusforming three spring edges, or lips oc, as shown in Fig. 3.

Beneath the crown e of my spring I preferably place the struck upannular supporting ring J. This serves as a support for the spring sothat the spring may be made of lighter 7o material and consequently moreflexible, but the said ring J may be omitted without substantiallyaltering the action of my spring.

It is obvious that I could hold my struck up bow curved annular lippedspring in other ways within the socket chamber without departing fromthe spirit of my invention.

I propose to use any of the well known forms of studs with this socketmember.

I claiml. In a fastener consisting of a socket member and stud member, asocket chamber provided with a struck up 4bow curved annular lippedspring C, substantially as described.

2. In a fastener consisting of a socket member and a stud member, asocket member consisting of a chambered eyelet Il, and a non resilientcollet I, and a bow curved annular lipped spring C, substantially asdescribed.

3. In a fastener consisting of a socket mem- 9o ber and stud member, asocket chamber provided with a struck up bow curved annular lippedspring, C and the ring J, substantially as described.

In witness whereof I have hereunto set my hand.
